TPO17 SYMBIOTIC RELATIONSHIP
最後一大題的選項
1. Parasitic relationships involve the interplay of aggression by the
parasite and resistance and adaptation by the host.
2. Mutualism ordinarily involves an interaction between two members of the
same species.
3. Mutualism is unique among symbiotic relationships in that it r benefits
both partners involved in the relationship.
4. Parasitic damage to Australian rabbits was never reversed because the
rabbits were unable to adapt to the parasites' attacks.
5. The rarity of commensal relationships stems from the difficulty of finding
relationships that benefit one species without affecting the other.
6. The structure of biological communities depends on the types of
relationshipsthat exist among the species within.
第三選項為什麼對? 他提到 "unique"
但是文中並沒有說mutualism unique
第六選項為什麼錯? 他提到 "types" 和 "species"
都是複數 就代表最後一段的 diverse connection
謝謝各位
